The father-of-four encouraged people to take part in the initiative, which sees consumers earn vouchers as they shop. Schools, nurseries, Scout and Guide groups and sports clubs can then redeem the vouchers for a range of cookery and sporting equipment.

"There are more ways than ever for schools, groups and clubs to use their Sainsbury's Active Kids vouchers - with loads of cooking and exercise equipment available - it's time to get collecting."
